In particular, the organization publishes "Threshold Limit Values for Chemical Substances in the Work Environment" and the "Documentation of TLVs." The TLV booklet is one source which may be used in hazard determination. www.acgih.org. ANSI—American National Standards Institute. ANSI is a coordinating body of various trade, technical, professional, and consumer groups who develop voluntary standards. www.ansi.org Acute—An adverse effect on the human body with symptoms of high severity coming quickly to a crisis. Acute effects are normally the result of short term exposures and short duration. Aerosol—This is a solid or liquid particulate, natural or manmade, which can remain suspended in air. Paint spray and smoke are examples of aerosols. Asphyxiant—A chemical, usually in a gas or vapor state, which displaces oxygen or prevents its use in the body by other chemical means. Assistant Secretary (OSHA)—"...means the Assistant Secretary of Labor for Occupational Safety and Health, U.S. Department of Labor, or designee." Autoignition temperature—This is the lowest temperature at which a substance will ignite and sustain combustion in the absence of an ignition source. Blood Agents—These are chemicals such as carbon monoxide and the cyanides which act on the blood and the hematopoietic system and ultimately result in depriving body tissues of adequate oxygen. Boiling point—The temperature at which a liquid changes its physical state to a gas. Toluene has a boiling point of 231°F.

  • Maleic Anhydride
    Maleic Anhydride 108-31-6 Hazard Summary Maleic anhydride is used in the formulation of resins. Exposure to maleic anhydride may occur from accidental releases to the environment or in workplaces where it is produced or used. Acute (short-term) inhalation exposure of humans to maleic anhydride has been observed to cause irritation of the respiratory tract and eye irritation. Chronic (long-term) exposure to maleic anhydride has been observed to cause chronic bronchitis, asthma-like attacks, and upper respiratory tract and eye irritation in workers. In some people, allergies have developed so that lower concentrations can no longer be tolerated. Kidney effects were observed in rats chronically exposed to maleic anhydride via gavage (experimentally placing the chemical in the stomach). EPA has not classified maleic anhydride for carcinogenicity. Please Note: The main sources of information for this fact sheet are EPA's Integrated Risk Information System (IRIS) (6), which contains information on oral chronic toxicity and the RfD, and EPA's Health and Environmental Effects Profile for Maleic Anhydride. (2) Other secondary sources include Hazardous Substances Data Bank (HSDB) (1), a database of summaries of peer-reviewed literature, and the Registry of Toxic Effects of Chemical Substances (RTECS) (3), a database of toxic effects that are not peer reviewed. Uses Maleic anhydride is used primarily in the formation of unsaturated polyester resins for use in boats, autos, trucks, buildings, piping, and electrical goods. Lube oil adhesives synthesized from maleic anhydride are used to prolong oil-change intervals and improve engine efficiency. (2,9) Maleic anhydride is also used to make copolymers, pesticides, and other organic compounds, and in Diels-Alder syntheses.

  • Toxicological Profile for Toluene
    TOLUENE 359 8. REGULATIONS, ADVISORIES, AND GUIDELINES MRLs are substance-specific estimates that are intended to serve as screening levels. They are used by ATSDR health assessors and other responders to identify contaminants and potential health effects that may be of concern at hazardous waste sites. ATSDR has derived an acute-duration inhalation MRL of 2 ppm (7.6 mg/m3) for toluene based on a LOAEL for minimally adverse neurological effects in a susceptible human population (Little et al. 1999). ATSDR has derived a chronic-duration inhalation MRL of 1 ppm (3.8 mg/m3) for toluene based on a NOAEL for neurological effects in humans in series of studies by the same group of investigators (Schäper et al. 2003, 2004, 2008; Seeber et al. 2004, 2005; Zupanic et al. 2002) ATSDR has derived an acute-duration oral MRL of 0.8 mg/kg/day for toluene based on a LOAEL for neurological effects in rats (Dyer et al. 1988). ATSDR has derived an intermediate-duration oral MRL of 0.2 mg/kg/day for toluene based on a NOAEL for immune depression in mice (Hsieh et al. 1989, 1990a, 1991). The International Agency for Research on Cancer (IARC) has classified toluene as a Group 3 carcinogen (not classifiable as to its carcinogenicity to humans) based on the evidence of carcinogenicity is inadequate in humans and inadequate or limited in experimental animals (IARC 2013). The World Health Organization (WHO) has not established any air quality guidelines but have concluded that further investigation would be needed before it was clear whether there was sufficient evidence to warrant their inclusion in the guidelines at present (WHO 2010).
